Abstract (en)
[origin: EP0188129A2] The present invention relates to a sintered product containing silicon carbide as a main component which comprises a phase (a) containing at least one metal selected from among AI, Sc, Y and rare earth elements and oxygen, a particle phase (b) comprising at least one metal carbide selected from among carbides of Ti, Zr, Hf, Va, Nb, Ta, W and the like, a composite particle phase (c) comprising said phase (a) and said phase (b) surrounding the phase (a) and silicon carbide matrix (d) in which the above phase (a), (b) and (c) are dispersed.The silicon carbide sintered product of the present invention exhibits a remarkably high strength and a remarkably high toughness which have not been attained up to this time, so that it can form various heat-resistant structural materials having a high reliability.
